' Referring 'new more particularly to tlie accompanying drawings.there is .shown a supporting traine.inf-ludiiiga column 1f` which is provided "with :rguitlchfivv 5, arms" l :2 Aand u. upon which latter is; mounted 'the 100 suppuriing pai-ts Il and 4. there being. a drive shaft (jouinaled' and'supported-in the arni Q and the cpliiinn '1. and at its outer endv prof.,

This table is 'provided Vwith a longitudinal groove gh along opposite sides of which are shoulders' 1'- upon which rest the pair ofA cleats l .adapt ed to overlap the preferably reduced edges t of the feed-bar lmounted in the aforesaid groove g, the can bodies 19 being adapted to rest upon the'cleats s or an otherpart o1 the tablev17 directly overt e feed-barl, and as thecans fed ,through the machine are of 'various diameters, I render the feed-'Way formed by the bars 38 adjustable by mounting the bars 38 so that they are movable tol i bar 38being preferably notchedv to provide a shoulder, .u adapted to overlap the lower vseam 'v ofthe can bodies 19 to prevent accidental forward movement of the bodiesy 19 out of the guide- Wayand also'to positivelyprevent lateral displacement. of 'the can bodies. These guide-way bars 38fare preferably held in adjusted relation to .providevarious widths of feed-Ways by means of the clamping elements lw secured on the table 17 bolts or other suitable fas,`

by Vmeans of the a bar which is adapted to 'be reciprocated horizontally on the table 17 the latter being re'ciprocal'atv a direct right angle tothe reciprocation of the feed-bar. The feed-bar Ais preferably provided Jvithta plurality .of

spaced 'openings 17 ,ione endof each/open-4 inghaving anV inwardly directed inclined shoulder 17L designed for coperation with the inclinededgel". of the can engaging dog 17 pivoted at 17d within the opening 1:7', with its inclined edge 17 held normally in,engagement with the shoulder 1 a through the instrumentality of a spring or equiva lent 17e, secured at one of its'ends to the underside of the dog 17 and at its opposite .end bearing upon a pin shoulder or the like 17fI These dogs 17e are adapted to engage 'the can bodies 19 when the feed bar is moved in one direction. as will be hereinafterex plained, and to be depressed into the open-A \in gs 17,when the feed-bar is moved in the opposite direction. so that upon' the reverse movement of the feed-bar, the dogs 17c will not dislodge. or in any Way interfere with the positions of the respective cans, by which latter the dogs are'depressed as they pass beneath the latter.

To reciprocate the feed-bar aA rod 12 is connected at one end to the eccentric 9 and at its opposite end pivotally connected tothe lcv/er'A 13 ixedly secured upon one end of the rock shaft b.' secured to and .movable with the table 17,'fthe vrock shaft having connected to its" opposite" end 4a lever 14 which ispivotally connected toone end of the link 15, .whpseppp'osite end is pivotally reciprocatin which slotA recip'r'ocatin fof the Vfeed-bar4 on thej table is permitted when the drive shaft. `isA driven, and the connections between the.

driveA shaft and Qfeed=bar consequently operated. By virtue of the connection of the rock shaft -b'to the table 17, the' feed-'bar is moved with the table in the vertical' recipro` cation of the latter.

Tol vertically reciprocate--thetable fa shaftv 6, the table isreciprocated ,.fttertially' mounted inthe lu c on theixnderside. of .the i of fee -bar 16,:therebe'ing a slot d inthe table 17, through which. theqlugc t depends from the feedbar and by'virtue of, i

The levers 33' are sustained in'the pulleys .35 andare revolved*therewith,-,thev being' mounted upon the pivot y' on the pulleys 35, and atptheir-upper ends'having adjustable elements, such as screws m, adapted to vbear at their inner ends againstfthe` annular wedge 'n lixedly secured to the lower en d of the split sleeve a mountedto 'rotate-.upon

thel collars 3Q. These elementsan bear `and effect rotation of the sleeve o---on the,

collars 3Q, and as the collars 32 are raised and lowered. as the result ofrreciprocation of the rods 30, the elements m fiile up and 'down the cam faces of the wedge 'members 1i to etect an opening and closing of the seam# mg elements or levers 33 uponl thelr' pivots j,

vas'will be obvious, "the operation of these seaming elements or levers 33 in their opening and closing operation being timed according to the reciprocatio of the tableand the reciprocation of the feed-bar. i

The lower ends of the pulley spindles 31 are providedwith chucks 39 which obviously do not revolve. but which enter the can head and hold the can firmly upon lthegtable andv prevent the 'can from turning. These chucks coperate with the table and the members: 3S in preventing vany movement of the can bodies 19 during the seaming operation. A'

It will now be understood that theicans4 receive two movements in their. course.

through the machine, that is. an up and' down movement and a horizontal movement in a straight line under the seaming or oper-l ating devices.

In operation the machine is' -set in motion. Thepulleys which carry the double seaming elements Yare `caused to revolve by a belt (not shown) which V3G. pulleys 35 and idler pulley 37. The table. which sustains the cans and the feedbar which moves them, work in unison with the double seaming rolls. which open and close vin proper relation thereto. The oper ator places a c an with its loose cover on the table at the extreme right in Fig. 1. The pawl. dog. or linger 17 in the reciprocating feed-bar engages the can body at the proper time. feeding it to the first set of rolls 34.4

where it receives an operation which in some cases ma)1 'complete it, but in' others itis 'carried to the next set of seaming elements, where it receives a second seaming operation. If necessary. other attachments may be placed in the line of feed to perform other operations, for instance. filling devices to fill thc cans. an automatic device for plae: ing the covers. etc. After the receptacle reis ejected by the a' receptacle at ceives its last operation. it last pawl or finger 1T 'into the extreme left. of the table.

Thenever aecan is' moved from the first. seaming device to a second one for furtherl operation. it will be seen that two cans are being operated on simultaneously, thereby eli'ecting a considerable saving in timeover methods in which' the cans must rece1 ve-a plurality of operations separately. The

feed bar reciprocates horizontally while 'and eject them automatically.'

passes over the pulleys the table.

'tion Aof the table.-

feed' table reciprocates vertically,`and also while thefeed table is stationary during the seaming operation, the feed bar at this timev making its backward stroke into position for feeding vforward successive cans. -.There can be no slopping of 4the contents ofthe cans or other receptacles incident to centrifuga'lv action, because the cans do not revolve. In practical operation the horizonl tal movementsv ofthe cans to 'feed them suc fiessively onejby one into registry with .the

'seeming mechanism-and the up :and down movements to clamp -them l. successiyely against theuppersta'tionary chuck plate4 are not suiicient in extent 'or rapldity to cause vslopping of the contents even .when the cans are filled with liquidrmaterials. The 'operator is at a safe distance from the 'revolving elements-of the machine, and all that is required of him is to place a can at the proper station ori-the machine table. The cans are then fed 'through the machine automatically, receiving lall operations necessary to seam What is claimed is 1.
